Description

[Detailed description of the invention]

[Industrial Field of Application] The present invention relates to a device for measuring the traffic volume of elevator passengers. [Prior Art] Normally, traffic within a building fluctuates constantly throughout the day. For example, in the case of an office building, there is a lot of traffic going from the entrance floor to the intermediate floor in the office during the morning hours when people are working, and conversely, when they are leaving work in the evening, there is a lot of traffic going from the intermediate floor to the entrance floor. many. Also, during lunch hours, there is a lot of traffic for assistants going from the middle floor to the entrance floor or the dining room floor, and in the latter half of the day, there is a lot of traffic going to the middle floor along the mine road. In addition, traffic is generally quiet in the early morning and at night, but during normal times known as business hours, there is a relatively large amount of traffic, and the traffic volume in the up and down directions is evenly balanced. The amount and structure of traffic within such a building (the way traffic flows between floors depends not only on the time of day but also on the purpose of the building (e.g. office, hotel, residential, etc.) and the characteristics of the floors (e.g. (1st entrance floor, dining room floor, office floor, conference room floor, etc.), and also depending on the day of the week and month. Conventionally, it has been necessary to drive appropriately in response to various busy traffic conditions that differ from building to building as mentioned above. To my friend, I divided the day into multiple time slots, detected the traffic condition values such as the car load, and aggregated and analyzed these values to select all the driving modes suitable for each time slot and drive. In addition, the number of hall calls, waiting time, and the number of people getting on and off each floor may be measured in order to diagnose whether the service provided by elevators currently in operation is appropriate. Various types of traffic measuring devices have been proposed for use in this purpose, depending on the measurement content, but among them, measuring the traffic volume of elevator users is the most important for controlling elevator operation. Conventionally, this method of measuring traffic volume involves measuring the car load using a pushing device installed on the car floor, as described in Japanese Patent Publication No. 59-8627, and calculating the amount of variation in the car load. There are methods to automatically measure the number of people getting on and off each floor by detecting the problem, and methods to manually measure the number of people getting on and off by placing measuring instruments in the elevator hall or inside the car. Problem] However, with the conventional measuring method using weighed coins, for example, 3
The traffic volume per floor can be measured, such as the number of passengers boarding from a floor and the number of people getting off at the third floor, but the traffic volume between floors can be measured, for example, the number of passengers moving from the third floor to the fifth floor (hereinafter referred to as Since it is not possible to measure the level of inter-floor traffic (referred to as inter-floor traffic volume), there is a problem in that it is not possible to drive appropriately according to traffic conditions. Furthermore, since the number of people getting on and off the train is detected by weight, there is a problem in that there is an error in the conversion, making it impossible to accurately detect the number of people. Furthermore, the above-mentioned manual measurement method requires many people and a huge amount of time, so it is impractical to carry out frequently and there is a problem that it is not possible to respond in a timely manner to constantly changing traffic. Ta. This invention has been made to solve the above-mentioned problems, and aims to provide an elevator traffic actual device that can measure floor mutual traffic TV with high precision and easily. . [Means for Solving the Problems] The elevator traffic measurement device according to the present invention includes a measuring device connected to an elevator control device to track the behavior of passengers in the car, and a measuring device that responds to the outputs of the elevator control device and the measuring device. The vehicle is equipped with a determining means for determining the behavior of passengers in the elevator car and detecting the boarding floor and alighting floor of each passenger, and a counting means for calculating the inter-floor traffic i by counting the outputs of the determining means, respectively. Ame with things. [Operation] The elevator traffic measurement device according to the present invention detects the boarding floor and the alighting floor of each passenger based on the output of the elevator control device and the output of the measuring means for tracking the behavior of passengers in the car,
Count floor inter-floor traffic. [Embodiment] Hereinafter, an embodiment of the present invention will be described based on FIGS. 1 to 6. The first [F] is an overall configuration diagram for clearly showing the configuration of an embodiment of the elevator traffic measurement device according to the present invention, and a 6-person car A is installed in a 5-story building and is installed at the top of the building. The elevator control device 6 is installed at the landings I on the first to fifth floors.
Hall calls and car calls corresponding to F to 5F are registered, and running, stopping, determining driving direction, opening/closing of doors, etc. are controlled in order to have the car & i respond to these calls. Furthermore, the traffic measurement device 7 connected to the elevator control device 6 is connected to a television camera 8AK installed inside the car, and tracks the movement of passengers in the car by analyzing all the images of the eight television cameras. A measuring means 8 outputs the position, and the behavior of the passengers in the car is determined according to the output signal of the measuring means 8 and the state signal of the elevator controller outputted from the elevator control device 6, and the It is comprised of a determining means 9 for detecting all boarding floors and alighting floors, and a counting means 10 for calculating the interfloor traffic volume by counting the output signals of the determining means 9, respectively. FIG. 2 is a block diagram showing the system configuration of the embodiment shown in FIG. This is a well-known dynamic displacement measuring device that separately tracks the movement of each designated passenger in the car and outputs the passenger's position as X-axis and Y-axis (backwards) position signals 83a to 87a. An example of an image taken by the television camera 8A is shown, and the X-axis and Y-axis of the dynamic displacement measuring devices 81 to 87 are adjusted in advance as shown in FIG. It is set near the entrance and exit of Bakago N, and is the measurement starting point P of the dynamic displacement measuring devices 81 to 86.
lo - P6o H are both at the coordinates (Xo, Yo), and the measurement start point P7o of the dynamic displacement measuring device 87 is the measurement start point Pl.
o = P6o and the coordinates (Xa,
Ya). Therefore, on the above X-Y coordinates, the interior of car A will be represented by the range XL≦X≦store and O≦Y≦night, and the entrance and exit of car A will be represented by X = XL and YLSY≦YH. Further, in this embodiment, the darkest point (corresponding to the passenger's head) of the image of the television camera 8N is detected. The center of gravity is set at 11 passenger positions P1 to P7, and the appropriate size is set in advance to the extent that it does not overlap with other passengers, taking into consideration the size when viewed through the television camera 8A from above the passenger's head. Keep window W1~
W7 i Set. By setting these windows W1 to W7, it is possible to track the movement of a given passenger without being affected by other scotomas even if there are many other scotomas (corresponding to the heads of other passengers). can. Automatic tracking command signal 9 for each of these dynamic displacement measuring devices 81 to 87]
When the automatic tracking command signals 91a to 97a are respectively set to "I", automatic tracking of the darkest point within the windows W1 to W7 is started. If you lose sight of the darkest point within windows W1 to W7 while tracking your own 1M1, the position data of that 1FufJ will continue to be output. and automatic tracking command signal 91a
.about.97a are respectively reset to rLJ, the passenger positions P1 to P7 are reset to the measurement starting point Pl. The process returns to ~P7o, and along with this, the windows W1 to w7 are also set to their initial positions and enter a standby state. The dynamic displacement measuring devices 81 to 86 are used to automatically track the movement of passengers in the car from the time they board the car to the time they get off the car, while the dynamic displacement measuring device 87 monitors the entry and exit of passengers mainly near the entrances and exits of the car. The position at the start of measurement of the window W7 of the dynamic displacement measuring device f187, which is used for detection in order to hand over the tracking of the friendly passenger to any of the other dynamic displacement measuring devices 81 to 86, is determined to be within the car. The window W7 is set close to the entrance so that passengers cannot enter the window W7. Furthermore, the background image f in the window W7 (that is, the image when there are no passengers in the window W7) 1 - The image in the window W7 obtained by storing this background image in advance and using the camera 8A Compare each time. Then, when there is a difference between the two (i.e., when a passenger enters the window W7 or the first time after entering the standby state, the passenger detection signal 887h'cr HJ) is output as a signal. It is informed by. 12 A measuring/counting device consisting of a microcomputer installed in the beach traffic measurement device 7, 0PU13, R0

In addition to the passenger detection signals 81a to 87a and the passenger detection signal 87h from the dynamic displacement measuring devices 81 to 87, the input circuit 16 receives signals related to the operating state of the elevator such as a car position signal 6a and a time signal 6b from the elevator control device 6. is input. On the other hand, the output circuit 7 outputs automatic tracking command signals 9111 to 97a to the dynamic displacement measurement devices 81 to 87, and also outputs a floor mutual traffic volume signal D to the elevator control device 6.

For ~87, automatic tracking command data becomes "1" when commanding automatic tracking, and becomes rOJ when ending automatic tracking, and when AT detects a new passenger to automatic tracking, it becomes @I-IJ, This is automatic tracking request data that becomes 1-OJ when any of the displacement measuring devices rn81 to rn86 is instructed to be an automatic tracker for the detected passenger. BO~823 is fixed data representing the boundaries of time zones divided every hour, and is set from 0:00 to 23:00, respectively. XL is fixed data representing the X coordinate of the entrance/exit of car N and is set to -100, and XH is the dynamic displacement measuring device fIt.
If the passenger detected by 87 enters the car any further, it will be determined that the passenger is a passenger. Fixed data representing the X coordinate of the boundary is set to -90. 51 is a 70-chart showing the entire nine operation program stored in the ROM 14 of the judgment/counting device [12], and FIG. 6 is a flowchart showing the subprogram in FIG. Next, the operation of the above embodiment will be explained with reference to FIGS. 1 to 6. The calculation program for the judgment/counting device 12 shown in Fig. 5 is by hand! if] 0 according to 01-118
．． First, in step 101, which is executed every second, a signal related to the rolling state is input from the elevator control device 6 through 16 input circuits, and the car position data CP and time data TIM]13 i Set. Next, in step 102, the automatic tracking request detection program detects whether or not a passenger who should be automatically tracked as a passenger has given up. This procedure will be explained in detail below with reference to FIG. In step 121 of FIG. 6, it is determined whether or not the dynamic displacement measuring device 87 is automatically tracking the passenger. If not, the automatic tracking command data TFL7 is "0", so proceed to step 122. , here it is determined whether or not a passenger is detected within the window W7. As mentioned above, window W
7 is initially set to a position where a passenger who is about to get on the train can be detected, but unless a passenger enters this window W7, the passenger detection data SX is rOJ, so the calculation of the automatic tracking request detection program 102 is continued as is. finish. If it is detected that a passenger has entered the window W7, the passenger detection data SX will be calculated by 1 operation IR:tA (=

From D hand 1 @ 122 to hand jilt 123-\ automatic tracking command data TR7 for advance dynamic displacement measuring device #87 is
1" and further outputs it through the output circuit 171 to set the automatic tracking command signal 97ai "HJ". Upon receiving this automatic tracking/command signal 97a'jz, the dynamic displacement measuring device 87 detects the passenger's behavior detected above. Although it will be fully automatic tracking,
Step 1 in executing the calculation program after the next calculation cycle
Since the automatic tracking command data TR7 is "1" at m121, the process proceeds to step 124, where a signal is input from the dynamic displacement measuring device 87 via the input circuit 16, and the position data PX7 and PY7 of the passenger being tracked is input. Set. Next step 125
In steps 128 to 128, it is determined whether the passenger being tracked is a passenger who has just gotten on the train or a passenger who is about to get off the train. If the passenger has just boarded the car, the X coordinate of the passenger position data P
X7 exceeds -90 and enters the basket and becomes PX at Yoneyu
7>XH is reached, so proceed from step 125 to step 127, set the automatic tracking request data T'irlJ, and in the next step 128 reset the automatic tracking command data rnrtrOJ for the dynamic displacement measuring device 87, and then set the output circuit. 17
The automatic tracking command signal 97a'ii-"L
Make it J. This completes the automatic tracking of the dynamic displacement measuring device 87, and returns to the measurement starting point P7° to prepare for the next passenger detection. If the passenger being tracked is a friend who is getting off the car, the X coordinate PX7 of the passenger position data becomes smaller than -100 and the passenger goes outside the car.
Therefore, the process proceeds to steps 125→126→128, where the automatic tracking command TR7 is reset to rOJ, and the automatic tracking of the dynamic displacement measuring device 87 ends. The position data of the passenger being tracked PX7 is [:XL
, XH], automatic tracking will continue. In this way, the automatic tracking request detection program 102 monitors all the comings and goings of passengers near the entrance and exit, and when a passenger whose subsequent behavior should be fully automatically tracked, that is, a passenger is detected, the automatic tracking request data AT is set to "1". is set to Next, in steps 103 to 115, dynamic displacement measurement! ! Based on automatic tracking by the devices 81 to 86, the boarding and alighting floors of passengers are detected and the inter-floor traffic volume is counted. First, in step 103, the variable ItrlJ is initialized. Step 1 for all dynamic displacement measuring devices 81 to 86 thereafter
04~] Repeating 15 becomes K. In step 104, it is determined whether or not the dynamic displacement measuring device in operation number is automatically tracking a passenger. If the automatic tracking is not in progress but on standby, the automatic tracking command data field (I) is "0" and the process proceeds to step 105. If no automatic tracking request has been issued here, the automatic tracking request data AT is "0", so step 114
In order to jump to and process the next dynamic displacement measuring device, the variable It-1 is increased. If an automatic tracking request has been issued (AT=rlJ), proceed to step 106,
In order to store the boarding floor of the passenger to be tracked from now on, the current car position data OP is set in the boarding floor data F (I). Next, in step 107, automatic tracking command data TR(I)'krlJ for the first dynamic displacement measuring device is set and outputted via the output circuit 17. The dynamic displacement measuring device corresponding to the variable (2) will now start tracking the detected passenger. Then, in step 108, the automatic tracking request data input Tt-rOJ is reset so that the next dynamic displacement measuring device on standby will not track the passenger twice. When automatic passenger tracking is started, the automatic tracking command data TR(I) is "1" from the next calculation cycle onwards, so the process proceeds from step 104 to step 109, where the input circuit -
A signal is input from a dynamic displacement measuring device corresponding to the variable work via 16, and passenger position data P X (I), P Y (
I) t-set. Then, it is determined at Senjo 110 whether the passenger has alighted or not, but while the passenger is in the car, the X coordinate PX(I) of the passenger position data is always a value greater than XL, so the process directly goes to step 114. and automatic tracking continues. If the car arrives at the floor targeted by the passenger being tracked, the passenger gets off and the X coordinate PX of the passenger position data is
When (I) becomes smaller than XL, the process proceeds to step 111, and the alighting floor data T (I
) sets the current car position data OP. Next step 1
At step 12, automatic tracking command data T R(T)'t r OI for the first dynamic displacement measuring device is reset, and this is outputted via the output circuit 17. The dynamic displacement measuring device corresponding to the variable work now finishes automatic tracking and returns to the measurement starting point and enters a standby state in preparation for the next automatic tracking. Then, in step 113, based on the passenger boarding floor data F (I) and the alighting floor data T (I) that have been tracked so far, the corresponding floor mutual traffic cumulative data D (F (I),
T(I)'t Count up by 1. In this way, when the process of detecting the boarding/disembarking floor and counting the inter-floor traffic volume is completed for all variables (=1 to 6), the process proceeds from step 115 to lamb 116. In step 116, it is determined whether each time period has ended. If the time has reached the end time of the time period, the time data TIME matches any of the boundary time data 80 to 823, so the process proceeds to step 117, and the floor mutual traffic cumulative data D(J , K) (J, ni=
1 to 5) are connected to the elevator control device 6 via the output circuit 17.
and is output to the recording device 18. Then, in step 118, floor mutual traffic cumulative data D (J, K
) (J, = 1 to 5) are all cleared to zero. In this way, the judgment/counting system [12 calculation programs]

Accordingly, the boarding floor and the alighting floor for each passenger are detected, and the inter-floor traffic volume is calculated. In this way, in the above embodiment, the movement of each passenger in the car is tracked by a dynamic displacement measuring device, and by combining this with the car position input from the elevator control device, the boarding floor and the alighting floor of the passenger are detected. friend. Based on this, the inter-floor traffic volume was counted and recorded for each time period. Therefore, it is possible to easily measure the traffic volume within a building at a detailed level such as the mutual traffic volume on all floors, with high precision. Furthermore, since the elevator is operated using the above-mentioned inter-floor traffic volume, it is possible to sufficiently perform an appropriate operation according to the traffic condition. FIG. 7 shows another embodiment of the present invention, and is a system configuration diagram when two heel units (six-seater) are installed side by side in a five-story building. 1, the elevator control device 6 registers and cancels hall calls, and communicates with a well-known group control device 60 that allocates the registered car No. 1 or No. 2 to the 9th hall call, and the car call and the assigned hall call. The well-known car control device 6 (1, 60B) controls the first car and the second car to respond respectively.
The traffic measuring device 7 is a measuring device installed on the car ceiling of the first car and the second car, each having a television camera 8 &8B'i, which tracks the behavior of passengers in the car and outputs the position of the passenger. 8 (l and 80B (corresponding to the measuring means 8 of the first embodiment), and the measuring devices 80A and 80B (corresponding to the measuring means 8 of the first embodiment).
Based on the passenger position signal from 0B and the car position signals from the car control devices 60A and 60B, all the boarding floors and alighting floors of the passengers in each car are detected, and the inter-floor traffic t is calculated. Judgment/counting devices 12A and 12B to output (same as the judgment/counting device 12 of the first embodiment) and floor mutual traffic signals from the judgment/counting devices 124 and 12B for No. 1 and No. 2 cars. It consists of an adder 19 that calculates and outputs the inter-floor traffic volume for the entire building by adding up the traffic volume between floors. This invention can also be applied to buildings. In each of the above embodiments, the measuring device for tracking passenger behavior uses an image from a television camera as an input signal, and tracks the darkest point of the image as a passenger. Although a dynamic displacement measuring device # is used, the measuring device is not limited to this. For example, the measuring device may be one that tracks the object based on input signals from an infrared camera, an ultrasonic oscillator, and a wave receiver. A receiver may receive a specific signal (for example, a radio wave) emitted by a passenger and track this as an input signal.Also, the color or lighting of the floor, walls, and door inside the car may be designed. It is also easy to distinguish between the background image and the passenger by Behavior can also be tracked simultaneously by time-sharing processing using a single dynamic displacement measuring device.In this way, a much cheaper traffic measurement device can be obtained.Furthermore, In the first embodiment, the dynamic displacement measuring device 87 is used to detect passengers to be automatically tracked.
The passenger detection method is not limited to this. For example, an ultrasonic transducer is installed above the entrance to detect passengers approaching from the landing, and the dynamic displacement measuring device 8 detects the passengers and tracks the passengers inside the car.
1 to 86 may be provided. Further, in the first embodiment, the first floor mutual traffic t is counted for each hourly time period, but the method of setting the time period is not limited to this. For example] 55+
You can set it in detail such as one unit or 30 minutes [2.
